SPEAKERS B AND C Binding posts: For use
with a single power amp. These left-right bind-
ing posts are provided for speaker pairs “B”
and “C”. You may connect only passive speak-
ers here. See fi gure B.
NOTE: If you’d like to use a pair of powered
speakers with your SRM-80A, do not connect
them to the “B” or “C” binding posts. Set the
AMP/SPK-B/C switch to the AMP- B/C po si tion.
Now you may use “A”, “B”, or “C” am pli fi er /
speaker line outputs for pow ered speakers.
FROM AMP OUTPUT: These Left-Right bind-
ing posts are provided to connect the Left
and Right speaker cables from the output of
your power amplifi er when the AMP/SPK-
B/C switch is set to SPK-B/C. The SRM-80A
routes these amplifi ed output signals to either
Speak er pair “B” or “C”, depending on which
Speaker select button you press on the front
panel or the SRM-RU remote unit. Be careful to
connect the output of your pow er amp to these
bind ing posts only. The relay that does the
switch ing is rated at 8A/240 volts. See fi gure B.
REMOTE: Accepts the cable for the optional
SRM-RU remote control unit. You will need to
use a 5 pin din type cable a midi cable will not
work properly.
MONITOR LINE OUTPUTS TO SPEAKER “C”
/POWER AMP IN: Use these Left and Right
1/4” phone jacks to connect a pair of powered
speakers or passive speakers with a power

a pair of powered speakers or a power amp
/ passive speakers. See fi gure A. When the
AMP/SPK-B/C switch is set to SPK-B/C both
B and C output signals will be present at these
jacks. The SRM-80A uses these jacks to send
either B or C output sig nals to your power
amp, and the power amp’s speaker output is
re turned to the SRM-80A via the FROM AMP
OUTPUT binding posts men tioned above.
From there, the SRM-80A sends the amplifi ed
signal to the passive speakers connected to
the SRM-80A’s “B” and “C” speaker binding
posts. See fi gure B.
